Codes and standards issued from different authorities such as National Fire Protection Association (NFPA) 780(1), lightning protection Institute (LPI)(2), underwriters laboratories (UL)(3) (USA) and also those given by both the Now the third revised edition of the English LIGHTNING PROTECTION GUIDE is available. Function Most lightning protection systems consist of three basic elements: air rods, cables and grounding electrodes. It is estimated that today 80% of churches and places of worship have a lightning protection system, and it is thought 90% of these are tower-only systems. Conclusion The most neglected part in many structures or buildings are protection against lightning. Lightning protection (Incorporating Amendment No. The recommendations mentioned in the previous section concerning the cabling and the connectors should be carefully taken into account; Circuit flow in case of lightning… For three decades, the LIGHTNING PROTECTION GUIDE from DEHN has been the trademark for practice-oriented technical literature in the fields of lightning and surge protection for buildings, installations and systems. Since only a mere vertical air terminal will not solve the purpose for protection of building unless the entire building is sufficiently protected either with: • Angle of protection method During the last few years a large number of lightning related accidents, especially due to direct strikes, have been reported from Asia and Africa where the lightning struck objects are small structures. The international standard for Lightning Protection referred as IEC 62305 – ‘Protection against Lightning’, (which is also accepted by many countries as national standard) especially adopted by Bureau of Indian standard as IS IEC 62305, in one of its part explains the need of planning, erection, testing and maintenance of lightning protection systems for building structures without any height limit. IEEE Guide for Direct Lightning Stroke Shielding of Substations 1. [5] NBC 2016: National Building Code of India: Part 8 Building Services, Section 2 Electrical Installations.

Lightning protection guidelines for aerospace vehicles (OCoLC)43673631 Microfiche version: Goodloe, C.C. » The down-conductors should form a direct continuation of the air-termination conductors The mesh spacing of the horizontal conductor should depend on the class of LPS as per tabulation of IEC 62305 Part 3 for mesh spacing. » The formation of loops in bring the down conductor shall be avoided, but where this is not possible the distance ‘s’ shall be maintained. This Lightning Protection Operative occupation is found in the construction, facilities management, heritage, infrastructure, transportation, utilities, petrochemical and energy production/distribution sectors. Since 1959, Mr. The maximum distance of any point on the roof from the nearest horizontal protective conductor shall be decided as per nature of LPS system and the level of protection. Lightning protection operative Details of standard Occupation summary. This standard, IEC 62305, consists of four parts and was Routing of down conductors through outer wall generally spoil the aesthetics of the building, due to which the down conductors are often routed through shafts, un-accessible areas, non-visible places etc. » When the distance from down conductors to combustible materials cannot be assured, the cross section of the down conductor shall not be less than 100 sq.mm. The installation should not be a vendor driven and only based on regulations as insisted by national or international standards and code. Since the post impact of lightning is too severe and disastrous care should be given at every level to ensure lightning protection is not provided for seeking statutory approvals. UL Marking and Application Guides are updated as necessary due to new product development, A proper lightning protection system (consisting of air terminal, down conductor, earthing) design is very important to ensure increased protection of a building against lightning and its effects. The book had to be revised and enlarged due to changes in standardisation and technical progress. The overviews illustrate the technical support available to project managers, chief … Chapter 5: The Certification Process reviews the history of aircraft lightning protection regulations and standards, and introduces the latest versions of these; most notably, the standards that have been published by SAE and EUROCAE since 1999. The author is also a representing member in CED46 committee for Electrical Installations of National Building Code, India. Dr. K. Janakiraman is an eminent speaker in the field of Lightning protection, Earthing and Surge Protection Techniques for the past 13 years. » Sizes and dimensions of components Lightning protection guidelines are developed by the National Fire Protection Association. BS EN 62305 protection against lightning is substantially larger than its predecessor and has been written and compiled by experts from around the world. Inadequately protected aerospace vehicles can be upset, damaged, or destroyed by a Lightning Protection Systems: US NFPA 780 vs BS EN 62305:2006. The location, height, and configuration of a structure play a big part in determining if a lightning protection system is necessary. Current Edition: 2020 Periodic maintenance, monitoring and certification should be made mandatory for the effective functioning of the protective devices installed. » Proper utilisation natural components as down conductor if applicable. In this case, an additional lightning protection device should be used between the antenna and the ODU for each of the 2 RF cables. All maintenance procedures shall be scheduled and carried out meeting the standard requirements in periodic intervals. What these systems are all about, how to install them properly, and why they provide additional security to a building and the equipment within it. Lightning Protection Guidelines for Aerospace Vehicles This technical memorandum provides lightning protection engineering guidelines and technical procedures used by the George C. Marshall Space Flight Center (MSFC) Electromagnetics and Aerospace Environments Branch for aerospace vehicles. » Usage of multiple connection with different materials should not be permitted. Having focus on power generation, transmission & distribution sectors; EPR brings in-depth analysis of the Indian and global power sector, interviews of eminent personalities, products innovation, case study, technological updates, features, projects & tenders, events update etc. CFPA-E No 4:2013 N Lightning protection CFPA-E®-GUI DELI NES FOREWORD The European fire protection associations have decides produce common guidelines in order to achieve similar interpretation in European countries and to give examples how damage from natural hazards can be effectively limited by preventive and defensive measures, normally learnt from experience. » A down-conductor should be installed at each exposed corner of the structure where this is possible. The recommendations mentioned in the previous section concerning the cabling and the connectors should be carefully taken into … [4] IEC 62561 part 1 – 7: Lightning Protection System Components (all parts).
